Summary
=======

Bugzilla is a Web-based bug-tracking system used by a large number of
software projects. The following security issue has been discovered
in Bugzilla:

* Even with account creation disabled, users can use the WebService to
  create an account.

All affected installations are encouraged to upgrade as soon as
possible.


Vulnerability Details
=====================

Class:       Unauthorized Access
Affected:    2.23.3 and above.
Description: Bugzilla::WebService::User::offer_account_by_email does
             not check the "createemailregexp" parameter, and thus
             allows users to create accounts who would normally be
             denied account creation.
             The "emailregexp" parameter is still checked.
             If you do not have the SOAP::Lite Perl module installed on
             your Bugzilla system, your system is not vulnerable
             (because the Bugzilla WebService will not be enabled).
